IMPROVEMENT INLITHOGRAPHIC-PRINTING- PRESSES.

The Schedule referred to in these Letters Patent and making pint of theam To all whom it may concern:

Be it known that I, Ancnsrn Hwronrrn MARI NONI, builder, of Paris,France, have invented Improvements in Apparatus for LithographicPrinting, and I do hereby declare that the following is a full, clear,and exact description of the same, reference being had to the annexedsheets of drawings, making a part of the same. My invention refers to anew or improved apparatus for lithographic printing. This I haverepresented in the annexed drawings, which make a part of the presentspecification.

Figure 1 shows an elevation view of the whole apparatus.

Figure 2 shows a plan view of the frame, the platecarrying slide, andthe motion thereof.

Figure 3 shows an elevation and its motion.

Figure 4 shows a section of the apparatus through ABODoffigs.2and3.

Figure 5 is a longitudinal section of the machine above the frame,showing the nip of the sheet by the printing-cylinder nippers, wherebyit is led on the strings, and also the strings which lead it on thereceiver, which lays it mechanically on the table.

Similar letters of referenceindicatc like parts in all the drawings.

"My invention consists First, in the combination,-with the reciprocatingcarriage of a cylinder lithographic press, of an adj ustable bed, upon;which the stone is placed for adjusting the stone, both vertically andlaterally.

Second, in a mechanism for lifting the inking-rollers from the stone, orinking-table.

Third, in the combination, with the receiving-cylinder, provided withgripers and cords or tapes, of the sheet-fliers To enable others skilledin the art to construct and use my invention, I will describe theconstruction and operation of the same.

The frame which supports the various parts offithe machine is formedofthe base-plate A and side frames B B, firmly bolted, or otherwisesecured together.

On the base-plate are secured two rails, on which the wheels E of thecarriage 0 travel, and two similar rails on the under side of thecarriage G rest on the wheels E. Motion is imparted tothe carriage bymeans of thetrain of wheels A B, the piiiions working the same, and theconnecting-rod and crank on the end of the main shaft, which hasbearings in an extension at one end. of the base-plate A.

The carriage 0 supports an adjustable bed, 0, on which the stone Z isplaced. The adjustment of this bed is mgulated vertically by the fourscrews D.

The printing-cylinder F, on which the sheet is reof the frame, theslide,

ceived from the feed-table, and held to receive the impression, isprovided with hearings in the upper part of the side frame B.

An arched frame, H, bolted to the frame, supports the mechanism whichreceives the sheet from the cyl iuder, and transfers it to thereceiving-table I. This mechanism is composed of a small cylinder, G,geared with the impression-cylinder, and provided with a set of gripersarranged on ashaft, and an arrangement of tapes, S S, and rollers, P,and a fly-frame, R, operated by the cam O on the main shaft, through themedium of the rod .N and lover P.

On the main shaft there is a cam-pin, which at each revolution operatesa lever secured to a shaft, from which project two arms, in which armsthe hikingroller has its bearings, and by the rocking of this lever theroller is alternately in contact with the reservoirm1ler-and the inkingt-able to, which gives a perfect supply of ink.

There is also, on the main shaft, a cam, which operates a rod, M, oneend of which is pivoted to a slotted, or toothed arm, in which a pin onone side of the impression-cylinder rests at proper intervals of time,and holdsthe cylinder at rest during the backward movement of the bed 0.A portion of the gear on the impression-cyliuder is cut away, so thatthe rack will pass under it, and at the proper time the cam-lever M,through the mechanism before described, re-engages the gear on thecylinder-head with the rack, and thus the impression-cylinder revolvesin one direction only, namely, with the forward motion of the carriage.

The impression-cylinder and the receiving-cylinder G are gearedtogether, and the geared teeth on the receiving-cylinder are aboutone-third longer than those on the impression-cylinder, and as'thatportion of the gear on the impressioucylinder which is cut away for thebackward travel of the carriage, is disconnected with the gear on thereceiving-cylinder, the connection is made by a toothed segment on theouter face of the gear on the impression-cylinder.

Both the impression and the receiving-cylinders are groovedlongitudinally for the-gripers and their mechanism. v

The gripers on both the impression and receivingcylinders consist ofcrank-shaft-B B, fig. 5, provided with griping-fingers D D, fig. 5,which shafts have bearings in the cylinder-heads; and upon the shaft ofeach there is secured an arm projecting opposite to the crank, which armrests upon a spring that shuts the gripers upon the sheet.

The gripers are opened by the crank travellingover cams of propershape,attached to the.fran 1e-work of the machine.

The, impression-cylinder is grooved, so that the gripers on thereceiving-cylinder can open into the groove and take hold of the printedsheet as it is carried forward by the impressioncylinder, and deliver itto the-tapes, which carry it to the fly. As the gripers form no part ofmy invention, a more detailed description is considered unnecessary.

The arrangement of the distributing, inking, and

I wettin g-rollers L K J, and ink-trough D, will be readily eccentricworking on a pin, to which is attached a handle, and by turning thehandle the rollers are raised 'from the stone, or form, as plainly shownin fig. 1.

Operation. The operation of the machine will be as follows:

The lithographed stone Z is laid upon the bed-plate.

O, which rests upon the travelling carriage O, and is properly adj nstedfor a perfect registeiyby the screws Q, as shown in fig. 4, and theink-fountain and rollers are properly adjusted to supply the ink.. Thesheets to be be printed are then fed from the table V to theimpression-cylinder F, when they are seized by the gripers and cariiedforward with the impression-cylinder and printed, and then delivered tothe gripers on the receiving-cylinder, which carry the sheet to thecords or tapes and rollers that deliver it to the fly, as plainly shownin fig. 5. The fly is then. operated through the medium of the cam O,and rod N, and

segment-arm P, which works in a pinion on the flyshaft, as shown in fig.1.

The rod N, which operates the fly, is reacted by a spring, applied inany proper way for the purpose.

The receiving-cylinder G is provided with grooves for the tapes to liein, so they will not come in contact with the .impression-oylinder, andall the taperollers are grooved for the tapes, excepting the rollerwhich is above the receiving-cylinder.

The roller located near the fly, is also grooved to receive the bladesor arms of the fly, so that they may he on a plane with the tapes, asthe sheet is delivered to them to be piled upon the table I.

The' importance of the .adjustable bed for lithographic printingwill beapparent. The stones are of variable thicknesses, and a perfectimpression is of the utmost importance. This is readily attained by me,by the means described.

Having thus fully described my invention,

What I claim, is-- 1. The combination, with the reciprocating carriageof .a cylinder lithographic press, of an adjustable bed, for adjustingthe stone, both vertically and laterally, substantially as described andspecified.

2. The T-shaped lifter, and its mechanism for lifting the inking-rollersfrom the stone and inking-table, substantially as described andspecified."

3. The combination of the sheet flier with an impression-cylinderwithout tapes, and a receiving cylim der, provided with both gripers andcords or tapes, substantially as described and specified.
